SKATE ATTACH M ENT.

SPECIFICATION forming part of Letters Patent No. 236,668, datedJanuary18, 1881,

Application filed November 17, 1880. (No model.)

To all whom it may concern Be it known that I, CHAR ES BREWSTER, of thecity and district of Montreal, Province of Quebec, Canada, have inventedcertain new and useful I Improvements in Skate Attachments; and I dohereby declare the following is a full, clear, and exact description ofthe same.

This invention has reference to further improvements in skateattachments, to cause in some respect a more desirable action of theparts forming the attachment, and in another or in others a cheaper formof construction.

In the drawings hereunto annexed similar letters of reference indicatelike parts, and Figure l is a side elevation of a skate embodying myinvention. Fig. 2 is a plan of front end of skate right side up. Fig. 3is a plan of front end of skate upside down, with runner removed. Fig. 4is a plan of heel end of skate right side up. Fig. 5 is a plan of heelend of skate upside down. Fig. 6 is a side elevation of amodification ofthe fastenings. Fig. 7 is a side elevation of Fig. 6. Fig. 1 is shown ona somewhat smaller scale than the other figures, which are about fullsize for an adult.

Letter A is the runner of the skate, provided with three projections, B,G, and D, for attaching the plates to, the front plate being attached toO and D by brackets E and F, one side of each bracket being riveted tothe runner and the other to the sole-plate A. The brackets E arefurthermore arranged to form guides to a T-shaped slide, G, as will beclearly understood from Figs. 1 and 3. This slide has its front edge, H,turned up at right angles, and portions I of the under side of the topbar of the T also turned up at rightangles,whereby said top bar isconverted into a groove for bold ing and guiding the shanks of theclamps K.

L is a slot cut in the body of G for the projections O to pass through,and of sufficient length to allow G to have all the necessary motion.

In the shank of each of the clamps Ka stud, M, having a button-head, issecured. The body of this stud comfortably fills the inclined slots N inthe sole-plate on the one side of the shank of the clamps, and thetransverse slots 0, cut in G on the other side. Its extremity isprovided with a washer, P, over which the end of M is riveted, thusforming a button or flange head on the under side.

R is a standard riveted into the T-slide G, having a screwed hole in itto agree with the screwed spindle B The sole-plate is provided with adepressed portion,O so that the button-heads of M shall not stand upabove the remaining portions of the surface of the sole-plate, and thusprevent the sole of the boot from resting fairly upon them. It willtherefore be seen that as the T-shaped slide G is moved backward andforward the clamps K are caused, by the action of the studs M, to bedrawn in and pushed out to gripe or release the sole of the boot placedupon the plate A. Furthermore, it will be seen that as the slide G ismoved toward the heel they (the clamps) move inward to gripe the boot,which is an important improvement, for it must be remembered that thefront part of 'the boot from the tip of the toe is tapered for aconsiderable distance, becoming larger as it approaches the heel, sothat by thus taking ad vantage of theform of the boot alarger range ofsize of boot for the same skate is provided for, as well as causing thefastening and unfastening of the clamps to be more quickly accomplished.

The projection B is provided with a recess at D for the reception of aplate, E (the section of B shown in Fig. 5 is 011 line av, Fig. 1,)which is simply cut to fit and then put in place in the recess. Theheel-plate I is provided with openings to fit corresponding projections,F formed on B, and these projections are entered into the opening in theheelplate and riveted over, when the whole is secured together, theplate E forming a guide and the riveting an attachment, the wholeforming a much cheaper and better guide than any of those at present inuse for the heelclamp slide K It will be seen that the stationary andfront clamps, L for the heel are made in one with the plate 1 While theclamps M for griping the rear of the heel, are made-in one with theslide K N is a standard riveted to the slide K and forms a bearing toreceive the journals and collared end of the spindle B to revolve in.(See Fig. 5.)

The slide K is so clearly shown in the drawings that no furtherdescription of it is considered necessary.

On the spindle B a Windlass-head is secured, by which, with the fingerand thumb, the spindle is rotated.

In the modification shown in Figs. 6 and 7 my invention is arranged toapply to griping the front part of the boot only, as some persons objectto have the heels of their boots, such as ladies fine boots, cut by theheel-clamps M It will therefore be understood that the sole-clamps shownin these two figures (6 and 7) may be used with almost any of theheelclamps in use that hold the heel independent of the sole. In thiscase the parts marked with the same letters of reference are the same asthose already described, only as follows: The T-plate G is cut shorterand the soleplate A made to extend back farther, and in it is secured astandard, S which corresponds in construction with that, N, alreadydescribed. The spindle B in this case is made short, as shown, butsimilarly operated by a capstanhead, S.

Instead of the brackets E shown in Figs. 1 and 3, two plates, E areprovided, set in a recess, D in projection (J, in a similar manner tothe plate E which has hereinbefore been described to be placed in therecess Din projection B, and the rear end of the plate A is attached toO in the same manner that the plate 1 has been hereinbefore described tobe secured to projection B. Thus it will be seen that the two plates Eform a perfect and cheaply-formed guide for the slotted shank of theplate G.

What I claim, and wish to secure by Letters Patent, is as follows:

1. The combination of the plate A, having inclined slots N, slide G,having slots 0, and clamps K, having studs M, with an operating device,13*, substantially as set forth.

2. The combination of the spindle B having Windlass-head S, with slideGr, constructed and arranged as described, to operate in conjunctionwith plate A and clamps K, constructed and arranged as described, andwith slide K also constructed and arranged as described, the wholesubstantially as set forth.

Y 3. The combination of the projection B, having recess D plate Eheel-plate l and slide K substantially as and for the purposes setforth.

4. The combination of the projection (l, having recess D plates E andslide G, substantially as and for the purposes set forth.
